Stochastic proof of the sharp symmetrized Talagrand inequality

Probability 2024-07-15 v1 Functional Analysis

Abstract

We give a new proof of the sharp symmetrized form of Talagrand's transport-entropy inequality. Compared to stochastic proofs of other Gaussian functional inequalities, the new idea here is a certain coupling induced by time-reversed martingale representations.
